Air pollution causes ‘huge’ reduction in intelligence, study reveals

Comments 0 Comment

The Guardian reports: Air pollution causes a “huge” reduction in intelligence, according to new research, indicating that the damage to society of toxic air is far deeper than the well-known impacts on physical health. The research was conducted in China but is relevant across the world, with 95% of the global population breathing unsafe air. It found that high pollution levels led to significant drops in test scores in language and arithmetic, with the average impact equivalent to having lost…

Vox reports: Ash and smoke are choking Seattle’s air for the second week in a row, as wildfires smolder in the Cascades and in British Columbia. The air quality in Seattle this week has been worse than in Beijing, one of the world’s most notoriously polluted cities. As of Wednesday morning, the Air Quality Index in Seattle was at 190, a rating classified as “unhealthy.” In parts of the city, the index rose as high as 220, which is “very…

The New York Times reports: Sitting for hours without moving can slow the flow of blood to our brains, according to a cautionary new study of office workers, a finding that could have implications for long-term brain health. But getting up and strolling for just two minutes every half-hour seems to stave off this decline in brain blood flow and may even increase it. Delivering blood to our brains is one of those automatic internal processes that most of us…

More than 2 billion people lack safe drinking water. That number will only grow

Science News reports: Freshwater is crucial for drinking, washing, growing food, producing energy and just about every other aspect of modern life. Yet more than 2 billion of Earth’s 7.6 billion inhabitants lack clean drinking water at home, available on demand. A major United Nations report, released in June, shows that the world is not on track to meet a U.N. goal: to bring safe water and sanitation to everyone by 2030. And by 2050, half the world’s population may…

Bayer stock plunges after jury awards man $289 million in Roundup cancer trial

Bayer stock plunges after jury awards man $289 million in Roundup cancer trial

Comments 0 Comment

The Washington Post reports: Bayer’s stock slumped more than 10 percent in trading Monday, three days after a California jury awarded $289 million to a former groundskeeper who said the popular weedkiller Roundup gave him terminal cancer. The stock drop sent a cautionary signal to the company that acquired Monsanto, the maker of the weedkiller, in June for $63 billion. The merger created the world’s largest seed and agrochemical company, marrying Monsanto’s dominance in genetically modified crops with Bayer’s pesticide…

Court orders Trump EPA to ban harmful pesticide

The Hill reports: A federal appeals court has ordered the Environmental Protection Agency (EPA) to ban the pesticide chlorpyrifos, which former Administrator Scott Pruitt refused to do last year. The decision is a major win for environmentalists and health advocates. The EPA’s own research, as recently as 2016, linked chlorpyrifos to developmental and neurological disorders, especially in children and infants. The Court of Appeals for the 9th Circuit said the Federal Food, Drug and Cosmetic Act, the federal law governing…

Clayton Dalton writes: Just a few years ago, infection with the hepatitis C virus guaranteed a slow and certain death for many. Available treatments were effective in about half of all patients, and the side effects could be awful. Things changed in 2014, when a new medication called Harvoni was approved to treat the infection. With cure rates approaching 99 per cent and far fewer side effects, the medication became an instant blockbuster. Sales topped $13.8 billion in 2015. But…

The marvel of LED lighting is now a global blight to health

The marvel of LED lighting is now a global blight to health

Comments 0 Comment

By Richard G ‘Bugs’ Stevens, Aeon Light pollution is often characterised as a soft issue in environmentalism. This perception needs to change. Light at night constitutes a massive assault on the ecology of the planet, including us. It also has indirect impacts because, while 20 per cent of electricity is used for lighting worldwide, at least 30 per cent of that light is wasted. Wasted light serves no purpose at all, and excessive lighting is too often used beyond what…

Olga Khazan reports: It’s fairly well known that a bad diet, a lack of exercise, and genetics can all contribute to type 2 diabetes. But a new global study points to an additional, surprising culprit: the air pollution emitted by cars and trucks. Though other research has shown a link between diabetes and air pollution in the past, this study is one of the largest of its kind, and it’s unique because it both is longitudinal and includes several types…

How the pharmaceutical drug economy became a racket controlled by Wall Street

How the pharmaceutical drug economy became a racket controlled by Wall Street

Alexander Ziachik writes: Donald Trump’s plan to lower prescription drug prices, announced May 11 in the Rose Garden, is a wonky departure for the president. In his approach to other signature campaign pledges, Trump has selected blunt-force tools: concrete walls, trade wars, ICE raids. His turn to pharmaceuticals finds him wading into the outer weeds of the 340B Discount program. These reforms crack the door on an overdue debate, but they are so incremental that nobody could confuse them with…

In a review of seven books on death and dying, Julie-Marie Strange writes: James Turner was twenty-five when his four-year-old daughter Annice died from a lung condition. She died at home with her parents and grandmother; her sleeping siblings were told of her death the next morning. James did everything to soothe Annice’s last days but, never having encountered death before, he didn’t immediately recognize it. He didn’t know what to do or expect and found it hard to discuss…

Michael Pollan writes: Just how soon might psychedelic-assisted psychotherapy be available aboveground, to the many people who stand to benefit from it? Before the F.D.A. approves a new medicine, the drug must survive testing for safety and efficacy in a three-stage sequence of trials, each of them involving a larger sample and more rigorous methods. When researchers recently brought to the F.D.A. the results of Phase 2 clinical trials of cancer patients who were given psilocybin and MDMA, they were…

The Guardian reports: A chemical found in the world’s most widely used weedkiller can have disrupting effects on sexual development, genes and beneficial gut bacteria at doses considered safe, according to a wide-ranging pilot study in rats. Glyphosate is the core ingredient in Monsanto’s Roundup herbicide and levels found in the human bloodstream have spiked by more than a 1,000% in the last two decades. The substance was recently relicensed for a shortened five-year lease by the EU. But scientists…

The Guardian reports: More than 95% of the world’s population breathe unsafe air and the burden is falling hardest on the poorest communities, with the gap between the most polluted and least polluted countries rising rapidly, a comprehensive study of global air pollution has found. Cities are home to an increasing majority of the world’s people, exposing billions to unsafe air, particularly in developing countries, but in rural areas the risk of indoor air pollution is often caused by burning…

The interstitium, the largest organ we never knew we had

Tanya Basu writes: What is an organ? Anatomy textbooks are rather fuzzy about what defines an “organ,” requiring one to have primary tissue—parenchyma—and “sporadic” tissue, called stroma, which can be nerves, vessels, and other connective tissue. Organs are the necessary building blocks of organisms (hence, the name), and can be gigantic or microscopic. So long as cells clump together to form tissues, and these tissues organize themselves into organs that perform specific functions in the survival of an organism, that…
